Abstract: Aphotoactive metal-organic complex[Zn2(BCbpe)2(p-DBC)2]∙

5H2O(1) has been synthesized based on an olefin-containing pyridinium compound, 1-(4-carboxybenzyl)-4-[2-(4-pyridyl)-vinyl]pyridinium chloride(HBCbpeCl), and characterized by single-crystal X-ray diffraction, IR spectroscopy, powder X-ray diffraction and thermogravimetric analysis, respectively. In the solid state, the BCbpe ligands are packed in a head-to-tail manner through weak cation-π interaction, undergoing a photo-induced cycloaddition quantitatively upon UV-light irradiation.
